This has been an interesting discussion, made more so by the falling Australian dollar. I think I will try to see what I can put together to replace my elderly, but not failing, Dynon battery back up pack.

Rather than cannibalise my existing battery can I ask if anyone knows the type of plug used on the Dynon Battery? I was thinking I would like to do something before the need arises.

From Dynon forum:

"Dynon Technical Support Staff member

The connector is a Molex 43640-0301, and the pins are 43031-0007. Sorry, but we can't supply these except as part of a harness."

Googling around I think that may be a typo as it reurns 3 connector parts.

Second being in Australia with a falling dollar. Haven’t tested mine as yet but are interested in the results as to if something is available locally for future reference.

Default Reconditioning Dynon Backup Battery

The correct part is the 3-pinned connector which only the two outer pins are used, not the middle one. I think I purchased mine from McMaster-Carr. Dan from Reno
